Description and usage notes:

Here at 1% in DEP, this is geosmin bought pure from IFF, diluted by Pell Wall and  so strong it must be used with great caution. 

Geosmin is the scent of warm earth, a freshly ploughed field, the first rain after a dry period, damp and deceptively powerful.

Geosmin doesn't seem particularly strong when you sniff the 1% solution, or even this 10% solution, but just a few drops can fill the room with the scent of turned earth. Traces in a fragrance can give you a unique effect and greatly increase diffusion. There really isn’t anything else like Geosmin, even though other materials, like 2-ethyl fenchol, have a superficially similar scent.

According to Brown University“Geosmin, which literally translates to ‘earth smell’ was scientifically identified more than 100 years ago. In soil, bacteria produce the chemical compound. In water, blue-green algae make it. Along with the pleasant scent of warm, moist soil, geosmin is also responsible for the muddy ‘off’ taste in some drinking water. That is why the substance is of interest to water purification experts and even vintners, who want to keep the benign but pungent substance out of their wine.”

Descriptions

Each entry contains a short list of scent notes with occasionally other short commentary to assist those who may not have encountered the material previously to decide whether it is of interest: I recommend you make your own assessment of each and every perfumery material you use however.

After pricing, quantity options and other basic details scroll down for narative descriptions: these are intended to assit interested readers as well as potential purchasers to assess the uses and potential of the material in question.

Many of the descriptions contain quotations from the manufacturer of the product and in addition I have quoted fairly extensively from Arctander[1] and from Arcadi Boix Camps[2] – both independent writers and both highly experienced perfumers.

There are also some quotes from Bedoukian[3] where details of the chemistry of a material are significant and from Scent & Chemistry[4] the authors of which have taken an analytical approach to the art of perfumery that is unusual and very useful. Quotations have been included from the extremely useful teaching books by Calkin & Jellinek[5] and Curtis & Williams[6] and Surburg and Panten [7] as well.

Anything not identified as a quotation is my own opinion of the material in question and it’s uses, but I am grateful to many other sources and perfumers as well as the expert authors named here.  Please note that these descriptions are copyright of the author and, other than properly achnowledged fair use quoations as defined in English Law, republication in any form is not permitted.

[2] Arcadi Boix Camps: quotations are taken from Perfumery: Techniques in Evolution, 2nd Edition published in 2009, but containing material written in 1978, 1985, and 1999 as well – where relevant the date of writing is noted with the quotations.

Spelling

A quick note about spellings: this website is primarily written in British English - it is after all written by an English Perfumer - however most of the authors mentioned here and many of the manufacturers were writing for American audiences and published using American English: where that is the case I have, as far as possible, preserved the spelling used in the source material.  As a result there may be inconsistencies on any given page, but that seemed to me better than arbitrarily changing material in the process of quotation.


Quantity Options

We’ve recently had a change of policy - and bought some new containers - so now all ingredients are sold by weight whether they are solids or liquids.  Only the 10ml and 5ml sizes incorporated in kits, and a few inexpensive materials such as solvents, are still done by volume.  Even the 5ml and 10ml sizes will now be filled to contain 5g or 10g regardless of whether the material is solid or liquid.

Liquids up to 10g in glass bottles (where the fill level may vary as illustrated above), 30g and 50g in HDPE Plastic.

Those materials available in 1Kg are normally supplied in aluminium flasks similar to those used for the 500g size, though we do supply a few materials in HDPE bottles as well.

Finally please note that, with some 500 different materials and so many size options we don’t hold ready-to-sell stocks: when you buy perfumery ingredients we will prepare them to order for you.  This means that large orders can sometimes take a few days to prepare and also that we don’t offer refunds on ingredients, unless of course there is a fault of some kind.
